GPU TF vs DC/LL data

[bcp19]

It seems obvious that there will be several factors involved when comparing GPU's; memory, clock, shaders, bus, etc. I broke it down to total exponents per day per GPU rather than say 1 @ 24 min + 1 @ 57 min, 2 @ 34 min, etc, for simplicity.

This is the rough capabilities of my 3:

Exp/day:
        GTS 450 GTX 560 GTX 560Ti
DC ^69  42      78      84
LL ^70  33      60      64
LL ^71  17      30      32
LL ^72  8.8     15      16
^69-72  4.9     8.5     9
Days/LL or DC:
        2500    2400    Q740    Core 2 Quad     GTS 450 GTX 560 GTX 560Ti
45M exp 0.033   0.030   0.059   0.054           0.029   0.014   0.013
Days    17.2    15.6    30.7    28.1            15.1    7.3     6.7
27M exp 0.017   0.016   0.035   0.031           0.0146  0.0071  0.0067
Days    5.3     5       10.9    9.7             4.5     2.2     2.1
CUDALuc ^68-69TF vs DC  ^69-70 vs LL    ^70-71 vs LL    ^71-72 vs LL    ^69-72 vs LL
560 Ti  ~176 to 1       ~429 to 1       ~214 to 1       ~107 to 1       ~60 to 1
560     ~172 to 1       ~438 to 1       ~219 to 1       ~110 to 1       ~62 to 1
450     ~189 to 1       ~498 to 1       ~257 to 1       ~133 to 1       ~74 to 1

The 450 has 512M memory as compared to 1GB in the 560/560Ti which is probably why it is less efficient at doing DC/LL when compared to TF. I also don't know how many factors per bit level are found, which is why I broke them down to 3 separate as well as including the 3 combined.
